Value Collection R63280269 Thumb Screw 3/8-16 Oval Head

Product Description

The VALUE COLLECTION R63280269 is an 18-8 stainless steel thumb screw with a 3/8-16 UNC thread and an oval head profile. Designed for hand-tightening applications, this thumb screw features a shouldered shank that seats positively against a mating surface without requiring a wrench or driver. The oval head measures 0.83 inches in diameter and 0.95 inches in height, giving the operator a firm grip surface. Overall length is 1 inch. The 18-8 stainless steel construction resists corrosion in moist or chemically active environments. Machinists, assembly technicians, and maintenance trades install this type of fastener wherever quick-release or tool-free adjustment is required.

This thumb screw is suited for light-duty mechanical assemblies, enclosures, fixtures, and equipment panels that require frequent manual adjustment or removal. The 3/8-16 UNC thread is one of the most common unified coarse thread standards in inch-based mechanical work, making this fastener widely compatible with standard tapped holes in that size. The with-shoulder design helps align the screw in the hole and limits pull-through in thin panels or plates.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or harsh environments
• 3/8-16 UNC thread standard for broad compatibility with standard tapped holes
• Oval head profile with 0.83 inch diameter provides a comfortable hand-grip surface
• With-shoulder design aids alignment and controls seating depth
• 1 inch overall length suits typical panel and fixture applications
• Tool-free installation and removal for applications requiring frequent access

Compatibility

Designed for use in any application with a standard 3/8-16 UNC tapped hole requiring a hand-tightened thumb screw fastener.

Installation Notes

Installation is performed by hand without a driver or wrench. Verify the mating tapped hole is clean and free of debris before threading in the screw. Do not use a wrench or driver to force the fastener beyond hand-tight torque, as this can damage the knurled head or strip the threads. Follow applicable mechanical or electrical enclosure codes when used in panels or equipment housings.
